Java In A Nutshell, 5th Edition

Signals that a thread should terminate. This error is thrown in a thread when the Thread.stop( ) method is called for that thread. This is an unusual Error type that simply causes a thread to be terminated , but does not print an error message or cause the interpreter to exit. You can catch THReadDeath errors to do any necessary cleanup for a thread, but if you do, you must rethrow the error so that the thread actually terminates.

public class ThreadDeath extends Error { // Public Constructors public ThreadDeath ( ); }
